The current version of SpotTrackTrack is
1.51.
This
version was released on 22nd November 2018; it adds
the ability to use fractions (1/2) instead of
percentages (50%) for levels. You can see the full
revision historyhere.

SpotTrack will
run in Demo mode indefinitely: enter
‘Demo’ as the user name. Note that the
demo version will only work with two spots, it
won’t print, and it’ll annoy you by
quitting every thirty minutes, but otherwise it works
just like the full version! It should give you enough
to let you decide if SpotTrack will be of use to you.
